Crowbits-Gas Sensor

What is Crowbits-Gas Sensor?

Crowbits-Gas Sensor is an analog input module used to detect the concentration of a gas in the air.

How does it work?

This module is a converter that converts a certain gas integral number into a corresponding electrical signal. It mainly uses the chemical potential difference between two electrodes. One electrode measures the gas concentration, and the other electrode is a fixed reference electrode. When the concentration of a certain measured gas exceeds the standard, the concentration value will be higher than the electrical signal of the reference electrode, and the module will output the corresponding concentration value. The higher the concentration, the higher the output electrical signal, thus achieving an early warning effect.

How to use it?

It is used together with the main board, and the gas sensor is used to detect the concentration of a certain gas in the air through programming. When the concentration reaches a certain critical value, an alarm is issued.
